1. Objectives: The purpose of this study was to analyze the serum lipid, digestive enzymes, thyroid hormone of each Sasang type groups which were classified by Sasang medicine specialist. 2. Methode: The subjects were 1084 (male:female=399:685) person with 371 of Taeeum type, 324 of Soeum type, 389 of Soyang type after the Sasang type classification. The blood samples of the 1084 subjects were to analyze the serum lipid(triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol), digestive enzymes(lipase, amylase), thyroid hormone(T3, TSH). The general linear model (SPSS 12.0) were used for the analysis. 3. Results: Taeeum type group ($133.50pm89.84$, $189.41pm33.11$, $107.29pm28.66$) showed significantly higher triglyceride, total cholesterol, LDL-cholesterol than other two group. In digestive enzymes(lipase, amylase), we found significant differences in the order of Soeum>Soyang>Taeeum. Soeum type group($116.23pm21.38$) has lower T3 than Soyang type group ($119.90pm21.60$) with marginal significance (p=0.066). 4. Conclusions: The Results of present study showed that Taeeum type showed significantly highest in triglyceride, total cholesterol, LDL-cholesterol. Soeum type showed significantly highest in digestive enzymes. Blood sample of each Sasang type group will serve as an important evidence for further study showing that the Sasang typology has biological basis.
